What researchers measure

Primary outcomes

  1. Number of Participants with One or More Serious Adverse Event(s) (SAEs) Considered by the Investigator to be Related to Study Drug Administration

    A summary of SAEs and other non-serious adverse events (AEs), regardless of causality, will be reported in the Reported Adverse Events module

    Time frame: Baseline up to Week 24

  2. Number of Participants Achieving a Validated Investigator's Global Assessment for Atopic Dermatitis (vIGA-AD) Score of 0 or 1 with a ≥ 2-point Improvement from Baseline

    The vIGA-AD measures the investigator's global assessment of the participant's overall severity of their AD, based on a static, numeric 5-point scale from 0 (clear skin) to 4 (severe disease). The score is based on an overall assessment of the degree of erythema, papulation/induration, oozing/crusting, and lichenification

    Time frame: Week 12

Secondary outcomes

  1. Maximum Observed Drug Concentration (Cmax) of LY3454738

    Cmax of LY3454738

    Time frame: Day 1 through Day 85 (Day 99 for Part C)

  2. Area Under the Concentration-Versus-Time Curve (AUC) of LY3454738

    AUC of LY3454738

    Time frame: Day 1 through Day 85 (Day 99 for Part C)

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Nov 2018 to primary completion in Sep 2021, 33 months.

Of 98 industry-sponsored phase 1 interventional studies under Dermatitis, Atopic, half reached primary completion within 13 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 21. This study's 33 months is above that.

Counting every sponsor, half of 116 studies reached it within 14 months; a quarter within 6 and three quarters within 21.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 6, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
